详细描述

The following types of KNXnet/IP structures can be encapsulated in QKnxNetIpFrame : QKnxNetIpHpai for host protocol address information (HPAI), QKnxNetIpCri for connection request information (CRI), QKnxNetIpCrd for connection response data (CRD) and QKnxNetIpDib for a description information block (DIB).

成员函数文档编制

QKnxNetIpStruct:: QKnxNetIpStruct (const QKnxNetIpStructHeader < CodeType > & headerField , const QKnxByteArray & dataField = {})

Creates a new KNXnet/IP structure with the specified headerField and payload dataField .

The header is expected to be fully set up and all values describing the payload are expected to match the specified payload.

注意： No adjustments are made to the function arguments.

QKnxNetIpStruct:: QKnxNetIpStruct ( CodeType codeType , const QKnxByteArray & dataField = {})

Creates a new KNXnet/IP structure with the specified codeType and payload dataField .

QKnxNetIpStruct:: QKnxNetIpStruct ()

Creates an empty invalid KNXnet/IP structure.

QKnxByteArray QKnxNetIpStruct:: bytes () const

Returns an array of bytes representing the KNXnet/IP structure including the header and the payload.

CodeType QKnxNetIpStruct:: code () const

Returns the generic code stored in the KNXnet/IP structure.

const QKnxByteArray &QKnxNetIpStruct:: constData () const

Returns the data stored in the KNXnet/IP structure.

QKnxByteArray QKnxNetIpStruct:: data () const

Returns the data stored in the KNXnet/IP structure.

另请参阅 setData ().

quint16 QKnxNetIpStruct:: dataSize () const

Returns the size of the data stored in the KNXnet/IP structure.

[static] QKnxNetIpStruct < CodeType > QKnxNetIpStruct:: fromBytes (const QKnxByteArray & bytes , quint16 index = 0)

Constructs the KNXnet/IP structure from the byte array bytes starting at the position index inside the array.

QKnxNetIpStructHeader < CodeType > QKnxNetIpStruct:: header () const

Returns the header stored in the KNXnet/IP structure.

另请参阅 setHeader ().

bool QKnxNetIpStruct:: isNull () const

返回 true if this is a default constructed structure; otherwise returns false .

bool QKnxNetIpStruct:: isValid () const

返回 true if the structure contains initialized values and is in itself valid; otherwise returns false .

另请参阅 isNull ().

void QKnxNetIpStruct:: setData (const QKnxByteArray & dataField )

Sets the data stored in the KNXnet/IP structure to dataField and updates the data size accordingly.

另请参阅 data ().

void QKnxNetIpStruct:: setHeader (const QKnxNetIpStructHeader < CodeType > & headerField )

Sets the header stored in the KNXnet/IP structure to headerField .

另请参阅 header ().

quint16 QKnxNetIpStruct:: size () const

Returns the size of the KNXnet/IP structure.

bool QKnxNetIpStruct:: operator!= (const QKnxNetIpStruct < CodeType > & other ) const

返回 true if this object and the given other 不相等；则返回 false .

bool QKnxNetIpStruct:: operator== (const QKnxNetIpStruct < CodeType > & other ) const

返回 true if this object and the given other 相等；否则返回 false .
